Strategies for better integrating nutrient supplementation and dietary diversity approaches for stunting reduction and improved nutrition outcomes: A Rwandan case study by Warner, James, Marivoet, Wim, Covic, Namukolo M., Umugwaneza, M.

“…Given that undernutrition calls for immediate action while food systems cannot be transformed overnight, abruptly implementing the diet diversity approach is neither effective nor politically feasible.Based on the article's findings, future policies in Rwanda should consider adopting a more comprehensive strategy that integrates a set of near‐term implementable health/nutrition interventions, for immediate impacts on stunting cases, with medium‐term investments to help establish a food system capable of increasing dietary diversity and sustainably improving nutritional outcomes of the population.…”

Measured growth and tree biomass estimates of Terminalia ivorensis in the three years after thinning to different densities in an agrisilvicultural system in southern Cameroon by Norgrove, L., Hauser, S.

“…These results suggest that, at least between 6 and 20 years of age, T. ivorensis has a linear, rather than a sigmoid or ε-function-shaped growth pattern and that the increased growth rate in response to thinning is maintained for the following years. …”

Point of care diagnosis of bovine trypanosomosis, tick-borne diseases and helminthoses with emphasis on portable anaemia-detection devices and decision support systems. by Magona, J.W.

“…The precision of the HCS (CV 2.9-8.8%) and HCU (CV 3.5-10.6%) was better than that of the DHT (CV 7.7-23%). There was good linearity between the readings of the HCS (R =: 0.925), HCU(R =: 0.920) and DHT (R =: 0.906) and those of the reference method (cyanmethaemoglobin). …”
